Sediment-Trap near Wedel

Expected effect

HPA and WSV consider the construction and the operation of this trap as maintenance work in a broader sense, aiming at reducing dredging costs. They are striving to further improvement of the overall sediment management and dredging activities by implementing this sediment trap.

The operation of the sediment trap enables flexible and effective maintenance work of the fairway. First of all, sedimentation is located within one defined area from which the sediments can be dredged more efficiently through the use of optimized equipment, e.g. larger hopper dredgers. Furthermore, after a longer period of sediment consolidation the hopper dredgers could achieve higher densities (i.e. dredging more sediments and less water).
